  • Patent number: 4141558
    Abstract: A plurality of golf balls are stored in a canister from which they are received by a vertical supply tube that supports the canister. From the tube, the balls move into a delivery arm that carries a release mechanism on its outer end. Actuation of the release mechanism when the arm is in its delivery position causes a ball to be dispensed onto a tee. The arm, which is supported by a sleeve surrounding the supply tube, can then be rotated about a vertical axis until it extends rearwardly and out of the way in a rest position. The supply tube is provided with openings with which the arm can be aligned on either side so that the apparatus can be operated in a right- or left- handed mode.
